Study of Transmission Characteristics of Optical Pulse in the Dispersive Fiber

Abstract:

Chromatic dispersion and nonlinearity effect are the two important factors affecting the optical pulse which propagates in the optical fiber. The former makes the pulse broaden, the latter mainly broaden pulse spectrum. Therefore, the linear and nonlinear dispersive propagation and control of optical pulses in the fiber has always been an important research topic of concern. In this paper, Starting from the nonlinear Schrodinger equation of the optical pulse and neglecting the chromatic dispersion, under the situation of chirp and chirp-free Gaussian pulse, we analytical analyzed, calculated and simulated the frequency chirp, pulse broadening factor and waveform of the Gaussian optical pulses in dispersion fiber. And numerical studied the waveform evolution of chirp-free super-Gaussian optical pulse with distance, analyzed the influence of optical pulse propagation by dispersion in different shapes and different initial chirp.
